Grape Ink (Permanent Marker × Grape Gas) – Hash Washing & Rosin Report

Strain Background & Resin Production

Grape Ink is the colloquial name for the cross of Permanent Marker and Grape Gas. Breeder info (sold as “Grape Pak” by NineWeeks Harvest) highlights this hybrid’s vigorous growth and heavy resin output ( Grape Pak – Nine Weeks Harvest) (Drops). The Permanent Marker lineage (Gelato/Biscotti family) contributes an unmistakable “soapy funk” aroma and strong trichome coverage, while Grape Gas (Grape Pie × Jet Fuel Gelato) adds extra resin and a sweet grape fuel terpene profile ( Grape Pak – Nine Weeks Harvest). Growers report that among various Grape Gas hybrids, this cross was a standout in resin production, essentially “all about the Perm” with added grease – suggesting it’s a promising washer for solventless extractions ( Grape Pak – Nine Weeks Harvest).

Community growers note Permanent Marker itself is a “hash-friendly” cultivar – it has made lists of top strains for making hash (What strains are we using to make hash??? : r/hash). Grape strains in general have a reputation for lower hash yields, but exceptional phenos exist. One hashmaker noted “sometimes the yields are not the best when it comes to washing grape strains”, though they “lucked out” with a particular grape cultivar that produced a “pretty nice yield percentage” (Some amazing grape hash rosin. About 14.3 grams, absolutely phenomenal : r/rosin). This implies Grape Ink could go either way depending on phenotype: some plants may lean toward the lower-yield “purple terp” side, while others (especially those showing Permanent Marker dominance) might dump ample resin. Breeder notes indicate heavy yields and loud terps are achievable ( Grape Pak – Nine Weeks Harvest). In Michigan, a collaborative wash of Permanent Marker was even hailed as one of the best rosin batches of the year, showing the extra special potential of this genetic line in extract form (Is this permanent before and after whip : r/rosin).

Rosin Color & Appearance

When processed optimally (fresh frozen input, minimal oxidation), rosin from this cultivar tends to come out very light in color. Fresh “live” hash rosin made from Grape Gas lineage buds is often pale blonde to near-white in hue ( Solventless Extraction Color Guide to Rosin – The Press Club ). For example, a 90µ ice-water hash rosin of Grape Gas was described as “almost a pure white color with a very smooth & buttery texture.” (Uplyfted | Grape Gas Live Rosin | 1g 1g Concentrates | Uplyfted ...) Likewise, Permanent Marker hash rosin is typically milky white to blond after cold-curing (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |). This suggests Grape Ink rosin will be on the lighter end of the spectrum (cream or light amber at darkest) if handled properly. High terpene content and minimal plant impurities give it a bright, blonde appearance – an off-white, ivory tone considered a hallmark of premium solventless extracts ( Solventless Extraction Color Guide to Rosin – The Press Club ).

(Luna Leaf - Grape Gas Hash Rosin - Dark Matter - Luna Leaf - Grape Gas Hash Rosin Near Me - Luna Leaf - Grape Gas Hash Rosin in New Mexico - Buy Luna Leaf - Grape Gas Hash Rosin) Example of a cured hash rosin (“cold cure”) from a Grape Gas cultivar, showing a creamy white/blonde color and buttery texture (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |).

Why so light? Freshly frozen material preserves terpenes and prevents the enzymatic browning that occurs in dried flowers. As a result, ice water hash made from fresh frozen buds yields rosin with pale hues, since the resin hasn’t oxidized or degraded much ( Solventless Extraction Color Guide to Rosin – The Press Club ). Darker rosin usually comes from cured/older input or higher-temp pressing. In fact, one extractor notes “all the dried [flower] I press comes out super dark – even worse when it’s older,” whereas fresh-frozen runs stay much lighter (Fresh frozen vs cured : r/CannabisExtracts - Reddit). Grape Ink will benefit from a live run: freezing the harvest immediately and washing soon after harvest to lock in those light colors.

It’s worth noting that color isn’t everything – an extremely white rosin could indicate under-ripe trichomes. The Press Club cautions that harvesting too early (clear trichomes) just to get water-clear rosin may “rob the resin of its full potential.” Fully ripe resin heads often have an amber tint that translates into a richer gold color in the extract ( Solventless Extraction Color Guide to Rosin – The Press Club ). In practice, cultivators let Grape Ink plants reach peak ripeness (some amber trichomes) to maximize potency and flavor, accepting a slightly deeper straw color in the rosin. The ideal hue is a light honey or cream color – a sign of fresh, peak-ripeness resin with minimal oxidation ( Solventless Extraction Color Guide to Rosin – The Press Club ) ( Solventless Extraction Color Guide to Rosin – The Press Club ).

First Press vs. Second Press Differences

After collecting the bubble hash, processors usually do a first press for top-tier rosin, and sometimes a second press of the same material to squeeze remaining oil. First-press rosin from Grape Ink will carry the brightest color and fullest terpene profile. It comes out as a light golden sap (if collected as fresh-press) or quickly butters into a blonde batter upon curing. The second press rosin is typically darker in hue – often a more amber/brown tone – and has a thicker, less “terpy” consistency. As one hash maker observed, “the second press was just as terpy and potent… only thing that suffered was the consistency and color.” (Second presses? : r/rosin - Reddit). In other words, pressing the hash again (usually at a higher temp or pressure) pulls out additional oils but also more oxidized compounds and plant waxes, dulling the appearance.

Expect first press Grape Ink rosin to look light and translucent (if kept as fresh press) or a creamy off-white (if cold cured into badder). It will showcase the strain’s grape-candy and chem funk terpenes robustly. The second press rosin will likely be a shade or two darker – perhaps a light amber – and may nucleate differently (sometimes second press oil can sugar up or be runnier, due to different cannabinoid/terpene content). Also, longer exposure to heat in second press can cause slight decarboxylation: more THC converts to CBN, giving a more sedative effect (Rosin FAQ - GreenDoor). Many commercial hash makers actually combine first and second press or do a single gentle full-duration press to avoid inconsistencies. But if separated, use the first press for dabbable premium product, and consider the second press for edibles or an infused pre-roll, where the darker color won’t matter as much.

Visually, side-by-side, you would see the first press rosin as a paler, more opaque blonde and the second press as a darker, slightly clearer amber. The first press badder will also tend to have a more stable, thick batter consistency, whereas second press rosin might be greasier or “sappier.” This difference comes from the extra lipids and less volatile compounds extracted in later presses (Second presses? : r/rosin - Reddit). In summary: first press = highest clarity and color, second press = darker and heavier. Both are usable, but connoisseurs prize that initial yield for its superior visual appeal and flavor (Second presses? : r/rosin - Reddit).

Optimal Micron Bag Ranges (Bubble Hash & Pressing)

When washing Permanent Marker × Grape Gas, extractors pay close attention to trichome head size. In ice-water extraction, the resin is typically sieved into several micron ranges. 90µ and 73µ bags catch mostly fully-formed gland heads and minimal stalks – this is the prime “first pull” hash. Many solventless artists will isolate the 90µ (or 73µ) fraction from Grape Ink and press that alone for the cleanest, highest-quality rosin (Rosin FAQ - GreenDoor). Hash rosin made from these mid-size heads tends to melt better and contain the richest cannabinoid/terpene content, which is why 90u “first wash” rosin often commands top dollar (Rosin FAQ - GreenDoor). One Michigan processor, Klutch, in fact markets a “90-159µ” Permanent Marker Live Rosin – indicating they press only hash in that range (skipping the smallest bits) (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates ...). The resulting concentrate is smooth and blond, as noted earlier.

On the other hand, full-spectrum hash rosin uses a broad range of microns combined. A common “full spec” selection is 45µ–159µ (sometimes including 25µ as well) (Rosin FAQ - GreenDoor). Pressing all grades together can give a more comprehensive terpene profile and entourage effect, since smaller heads and even partial trichomes contribute different compounds (Rosin FAQ - GreenDoor). Some extractors do report that Grape Gas (and thus Grape Ink) washes yield most of their resin in the 90µ–120µ range, with less coming in the 45µ bag (certain grape-heavy strains might have larger gland heads). One grower’s post in r/Rosin2 showed Grape Gas bubble hash collected across 45–159µ being pressed into a beautiful rosin (Grape Gas 45-159u : r/Rosin2) – implying they ran full-spectrum and were happy with the result.

What’s recommended? For premium rosin, you could keep 90µ (and/or 73µ) heads separate. This ensures maximum clarity and will give that “melty” quality connoisseurs love (Rosin FAQ - GreenDoor). Expect Grape Ink’s 90µ hash to produce the lightest-colored rosin. The 120µ bag may catch some good heads too (especially if the cultivar produces larger trichomes); some hash makers lump 90µ-120µ together as the “A-grade”. 45µ and 25µ fractions often have broken or immature heads – rosin from these can be darker or oilier, so they might be reserved for a “2nd press” or blended into edibles (Rosin FAQ - GreenDoor). That said, including a bit of the 45µ can round out the flavor with additional terps that the big heads missed (Rosin FAQ - GreenDoor).

In practice, many will do a full spec wash (45-159µ) for yield, then decide at press time whether to separate grades. If the goal is maximum output (e.g. in a production environment where total grams matter), pressing full-spectrum will net more rosin at once, albeit with a slightly darker color than a isolated 90µ press. If the goal is an award-winning gram, press the cream of the crop (90µ “first wash”). For example, one forum post about a similar cross (Permanent Marker × King’s Kush) noted the hash was collected in the 73µ–159µ range (Is this permanent before and after whip : r/rosin), indicating the washer focused on the higher grade heads.

Press filter bags: Whether using a 25µ or 37µ rosin filter bag for pressing can also impact clarity. Some pressers opt for a tighter 37µ filter when pressing hash to catch any fine sediment, with negligible loss in yield (permanent gas (sour diesel x permanent marker) one gram yield from an eighth! 165f 160u : r/flowerrosin) (permanent gas (sour diesel x permanent marker) one gram yield from an eighth! 165f 160u : r/flowerrosin). Others find a 25µ screen yields the absolute cleanest rosin at the cost of a little flow. If pressing just flower (less common for this strain since it’s wash-friendly), a larger mesh like 90–160µ bag is used to prevent blowouts (permanent gas (sour diesel x permanent marker) one gram yield from an eighth! 165f 160u : r/flowerrosin) – but for bubble hash rosin, stick to ≤37µ filter for best results. In summary, isolate 90µ/73µ for top quality, or press 45–159µ full-spec for a balanced, higher-yield output (Rosin FAQ - GreenDoor). Both approaches have been successfully applied to Grape Gas and Permanent Marker genetics in the community.

Curing, Grease-Outs, and Color Changes

After pressing, rosin consistency will evolve, especially with this terp-rich cultivar. Freshly squished rosin (especially if immediately cooled) often starts as a translucent, sap-like oil. Over time – particularly under cold cure (left in a jar at room temp or slightly warmed, then “whipped”) – the Grape Ink rosin is likely to “butter up” or grease out into an opaque batter. This is a desirable change; it indicates THCa crystallizing and terpenes homogenizing, resulting in that cake batter or wet crumble texture. As a solventless FAQ notes, “some strains may naturally turn into a creamy texture over time, even when stored cold.” (Rosin FAQ - GreenDoor) Permanent Marker crosses fall into this category – they tend to nucleate readily.

Processors report that a cold cure (e.g. letting the first-press rosin sit in a jar for a few days, then stirring) yields a stable badder with improved handleability. The color often lightens further upon this curing/whipping. For instance, Klutch’s cold cure Permanent Marker rosin appears almost chalk-white in certain batches (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |). During the cure, trapped air and the separation/recombination of terps can give a matte, butter-like look (versus the glassy appearance of fresh press). This phenomenon is commonly called “greasing out” – the rosin becomes wet and greasy on the surface as terpenes bleed, then it all whips into a uniform dough. Expect Grape Ink rosin to grease out quickly given its high oil content. Many hash makers actually prefer this: the whipped rosin is easier to dab (no need to preheat), and the flavor often blooms after a short cure.

Are there any unexpected color changes? With some strains, prolonged cure can darken rosin (especially if stored warm). In the case of Grape Ink, most anecdotal evidence points to it retaining a light color post-cure – if anything, going from translucent golden to an opaque blonde. One should store the rosin in a cool, dark place to preserve that shade. If left in a hot environment, even a white rosin can “sugar” or get a bit darker due to oxidation. But under proper storage (< room temp, minimal light), this cultivar’s rosin should stay a buttery off-white. Grease-outs typically manifest as a layer of wet, glossy oils on top of a matte base; once fully nucleated and mixed, the final product is uniform. In product photos, Grape Gas and Permanent Marker rosins cured into a badder have a pale blonde, dough-like appearance (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |), indicating this cross will behave similarly.

No significant “auto-budder” issues beyond the norm have been reported – in other words, Grape Ink doesn’t have any negative instability beyond the expected greasing. If anything, it wants to butter (which is a good thing for most extract artists). One could even fresh-press and shelf-cure it to the desired consistency without whipping, and it will likely wax up on its own in a week or two. In summary: anticipate a wet, creamy badder after curing, with maybe a shade lighter color than the initial fresh press. This is typical and desirable, not a sign of degradation (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |).

Harvest Timing & Material Freshness Effects

Harvest timing is crucial for both yield and rosin quality with this cultivar. As touched on earlier, harvesting too early (mostly clear trichomes) might give water-clear rosin but at the cost of potency and flavor. Optimal harvest for hash is usually when trichome heads are mostly cloudy with a touch of amber – this indicates peak resin maturity. At this stage, the resin will be rich in cannabinoids and terpenes, and pressing it will yield a potent, flavorful rosin with a slight golden tint. The Press Club guide explicitly notes that “a very light color…could indicate the resin was harvested too early…It’s best to let [the resin] mature fully on the plant… which means it will start to turn an amber color” ( Solventless Extraction Color Guide to Rosin – The Press Club ). In practice, many solventless growers harvest on the earlier side of ripe (few ambers) to balance potency and color. For Grape Ink, you may target a harvest window when pistils are mostly brown and trichomes milky, with say 5-10% ambers. This ensures you’re not chopping unripe, but also not so late that trichomes are falling off or degrading.

Freshness of material is another key factor for rosin color and yield. Grape Ink should be processed as fresh frozen for best results. This means chopping the plants and freezing within minutes, then doing the ice water wash within a short time (days to weeks). One hash maker who produced top-notch Grape Gas hash noted it was “chopped and frozen within 5 minutes, washed the next day” and then freeze-dried immediately, resulting in pristine blonde hash (Grape gas hash, no you can't press it, it's exactly how it should be). Rapid freezing preserves terpenes and prevents any microbial growth or oxidation that could darken the resin.

If one were to use cured flower or trim, expect a darker, lower-terpene rosin. As an extractor bluntly put it: “Fresh frozen is best… all the dried material I press comes out super dark” (Fresh frozen vs cured : r/CannabisExtracts - Reddit). Drying and curing introduce oxygen, which oxidizes terpenes and cannabinoids (think of an apple turning brown when exposed to air). This oxidation yields amber/brown hues in the final extract ( Solventless Extraction Color Guide to Rosin – The Press Club ). Therefore, to get that white/cream “Grape Ink” rosin, start with fresh frozen buds. If using cured input (perhaps for experimentation), consider lower press temps and very short wash agitation to mitigate the darkness, but it likely won’t match the liveliness of live rosin.

Harvest timing also affects yield: Letting the buds ripen fully can increase resin yield up to a point – past a certain peak, trichomes may start to degrade or drop, which actually reduces yield. Monitoring resin heads with a scope is advisable. Many growers find a sweet spot around 63–70 days of flower for strains of this lineage (the seed vendor lists ~63 days bloom for Grape Pak) (Drops). If pulled significantly early, the hash yield might be lower (smaller heads, less dense resin) even if the color is pale. If pulled too late, resin heads can get over-mature (fragile, or converted to CBN). The goal is maximum milky heads – at that point the plant’s resin glands are swollen with THC and terps, ideal for washing.

In summary: freeze fresh, don’t dry if possible; harvest at peak ripeness, not peak emptiness. By doing so, you ensure Grape Ink produces light-colored, terpene-rich rosin without sacrificing potency. The end product will reflect the care in timing – a slightly creamy platinum blond rosin that still packs the full “grape marker” flavor.

Community Feedback & Yield Data

Being a relatively new cross, direct public data on hash yield percentages for Permanent Marker × Grape Gas is limited. However, we can draw insights from the parents and similar strains:

Grape Gas (Cut) – Known growers of the CLTVTD/Compound Grape Gas cut have reported medium-high yields in hydrocarbon extraction, and in solventless some have achieved 3.5%+ yields (fresh frozen to rosin) (So pretty new to this and used a toll processor. Strain is Eastside Og ...). In one discussion, a processor noted many people getting “3.5%+++ off the [Grape Gas] cut”, whereas an inexperienced run might yield less. A community-sourced list of wash results listed Grape Gasoline at ~3.58% yield to hash and ~2.78% yield to rosin (from fresh frozen) (Strain list with yield reports | The Canna Cabana). This suggests ~75–80% hash-to-rosin conversion efficiency and a solid but not top-tier return. By comparison, some “washer” strains like GMO or Papaya can hit 5-6% FF yields, whereas many purple or dessert strains struggle to reach 3%. Grape Gas at ~3-4% is respectable, and if Permanent Marker boosts the resin, Grape Ink could be in that range or higher.
Permanent Marker – As Leafly’s Strain of the Year 2023, Permanent Marker gained fame not just for its nose but also for extractability. Growers have anecdotally found it to yield a “medium to high” amount of hash (Tier 2 – Cannabis Clones). One clone vendor describes its hash yield as “medium to high” as well (Tier 2 – Cannabis Clones). In Michigan, Eastside Alchemy’s wash of a Permanent Marker cut produced a notable amount of rosin (selling out quickly), though exact numbers weren’t published. Given its Gelato/Biscotti heritage, one might expect 4% range yields from fresh frozen (Gelato isn’t known as a washer, but Biscotti and Jealousy can produce decent resin). The combination of these genetics could synergize for better yields than either alone – Grape Gas contributes hash-friendly traits and Permanent Marker brings density of trichomes.

First-hand reports: On forums and Reddit, early testers of Grape Ink (sometimes referring to specific phenos as “Permanent Grape” etc.) have shared mixed but generally positive feedback. A few key points from community discussions:

Resin quality: The rosin is said to be extremely flavorful, merging the sweet grape-candy notes with a strong chemical gas backend. One Missouri caregiver noted Permanent Marker had a “grape scented marker” aroma (Permanent Marker Review : r/MissouriMedical - Reddit), which absolutely carries into extracts. Users who’ve dabbed rosin from this cross report a tangy grape inhale and lingering fuel/Sharpie taste on the exhale, indicating terpenes like linalool, limonene, and chemical esters are present in force (lab data from Klutch shows ~3.7% total terpenes, dominated by limonene and linalool) (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |).
Yield anecdotes: No one has posted an exact wash % for Grape Ink publicly yet (as of 2025), but those who have run similar crosses often cite “above average wash, not record-breaking.” For instance, a grower of a Lemon Cherry Gelato × Grape Gas × Permanent Marker hybrid reported “moderate yield…quality of the buds makes up for it” (Cherry Gas Marker Strain Review and Information | 2025). This hints that while you may not get huge return like a hash-plant, you’ll still get a decent amount of gorgeous rosin. If we estimate, a well-grown batch of Grape Ink fresh frozen might yield ~4-5% hash (by weight) on the first pulls. Pressing that could give ~3-4% rosin yield from the fresh weight. In a production environment, you’d likely aim for ~3%+ rosin yield to be satisfied. Lower than 2% would be disappointing (possibly indicating a poor wash or a bad pheno), whereas anything above 4% would confirm you have a “dumper” cut.
Bubble hash quality: Several hash makers care about whether the cultivar makes full-melt six-star hash (usable as dabble hash without pressing). While no specific melt reports for this exact cross were found, Grape Gas has produced excellent 5-6★ bubble in some runs (one Redditor showing off Grape Gas hash said it was “exactly how it should be” and didn’t even need pressing (Grape gas hash, no you can't press it, it's exactly how it should be)). Permanent Marker, being new, isn’t widely reported as full-melt or not – but given its trichome density, it likely produces at least 4-5★ hash that presses clean. If full melt is a goal, one might test different phenos: a Permanent Marker-leaning pheno might have more waxy heads that need pressing, whereas a Grape Gas-leaner could potentially yield cleaner bubble. So far, processors have treated Grape Ink as primarily a hash rosin strain rather than true melt hashish.
Tips from the field: Keep wash water cold and don’t over-agitate – grape and Gelato family strains can “grease” in the wash if overworked, potentially smearing oils and hurting yield. Several washers mentioned that gentle hand-washing or using a fine tuning (shorter wash cycles) helped maximize yields on Grape Pie/Gelato genetics. Also, do multiple washes of the same material. The first wash might pull the cream (90u heads), but second and even third washes can bring out additional resin from those Permanent Marker buds. One hashmaker on Facebook shared their tech for Grape Gas: 159-45µ bags, 25µ work bag, 3 minute warm-up, press at 169°F for 2 minutes at 6k PSI (All you had to do is include tech info. ‍♂️ - Facebook) – indicating fairly standard rosin press parameters for live hash. They achieved around ~70% yield from hash to rosin with that approach, which is in line with expectations.

Conclusion & Recommendations

Grape Ink (Permanent Marker × Grape Gas) shows great promise as a solventless extraction strain. Extract artists can expect a pale, creamy white rosin with a bold terpene signature, especially when using fresh frozen material and cold cure techniques (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |) (Uplyfted | Grape Gas Live Rosin | 1g 1g Concentrates | Uplyfted ...). The first press rosin will be the star – white/cream in color, stable badder consistency, and bursting with sweet grape and chemical funk terps. A second press can be performed for additional yield, though the rosin will come out darker and heavier-bodied (Second presses? : r/rosin - Reddit).

For optimal results in production:

Harvest/Material: Harvest at full maturity (mostly cloudy trichomes) for peak oil content – do not chop early just for color ( Solventless Extraction Color Guide to Rosin – The Press Club ). Freeze immediately and process as live hash to retain light hues and max terpene content (Fresh frozen vs cured : r/CannabisExtracts - Reddit). Avoid using dry/cured trim; it will make darker, less desirable rosin.
Wash Technique: Use very cold water and consider 2-3 short washes rather than one long wash. This prevents over-extraction of plant matter. Grape Ink’s resin is abundant but treat it gently to avoid “greasy” emulsions. Work bag: 220µ or 250µ, collection bags: at least 160µ, 120µ, 90µ, 73µ, 45µ (and optionally 25µ) to separate grades.
Micron Selection: For top-shelf SKUs, isolate the 90µ (and/or 73µ) hash – this will yield the cleanest, whitest rosin (Rosin FAQ - GreenDoor). The 120µ can also be very good if the trichomes are larger. You can label this as “1st pull 90µ rosin” for connoisseurs. For bulk production, a full spectrum 45-159µ blend can be pressed to maximize output, giving a slightly more amber but still high-quality rosin (Rosin FAQ - GreenDoor). Many operations combine 73–159µ as “Tier 1” and use 45µ separately as Tier 2 or edibles input.
Pressing: Ideal press temp for live bubble hash rosin is ~160–175°F (71–79°C). Lower end of that range preserves color/terps, higher end yields more. Starting around 165°F is a good balance for this strain, as it retains volatile grape terps while still yielding ~70-80% of the hash weight in rosin. Use a 37µ or 25µ rosin filter for the cleanest output. Pressure in the 500–1000 PSI (bag pressure) range is sufficient; avoid going too high which can blow out or introduce particulates. A slow, low-pressure ramp and a brief hold (sub-2 minutes) will minimize darkening. As observed, pressing in this way has produced impressively light-colored rosin even from Grape Gas whole plant hash (permanent gas (sour diesel x permanent marker) one gram yield from an eighth! 165f 160u : r/flowerrosin).
Post-Processing: Jar the rosin and let it cold cure (room temp) for a few days to a week. You’ll notice it likely “greases out” within 24-48 hours – at that point, stir or whip it to a uniform batter. The final product will be a wet, doughy budder that is easy to handle and dab. This process often brightens the color further and deepens the aroma (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |). Storage: Keep the jars cool (50-60°F if possible for long term) to prevent any terpene loss or darkening. Properly cured, the rosin is stable; consumers can even keep it at room temp short-term without significant sugaring.
Yield Expectations: Aim for at least 3% rosin yield (of fresh frozen weight) to consider the run successful. Top phenos could approach 4-5%. If running 1000g of fresh frozen, for example, a yield of ~30g rosin would be decent; anything above 40g would be excellent. One source’s data suggests ~2.8% rosin from Grape Gas (Strain list with yield reports | The Canna Cabana), so with Permanent Marker influence we’re hoping to hit or beat that. Track yields from each wash and each micron fraction – this will help identify which pheno or harvest batch performs best, and whether most of the resin is in the high micron (90µ+) or lower.

In conclusion, Grape Ink is a solventless processor’s delight: it can produce beautifully light-colored rosin with the coveted creamy “white” look (| Permanent Marker 90-159u Live Hash Rosin | 1g Concentrates | Klutch |), especially from the first press and prime micron heads. Its terpene profile is loud and unique, combining grape candy, floral notes, and sharp gas – a profile that really pops in bubble hash and rosin form. While yields might not shatter records, they are solidly in the profitable range (comparable to many modern exotics). With careful harvest timing, proper cold chain handling, and technique, an extract artist can pull gorgeous hash and rosin from Permanent Marker × Grape Gas that will impress both in the jar and on the nail. As one hashmaker put it when discussing grape cultivars: “I had a pretty nice yield…and the flavor is super clean” (Some amazing grape hash rosin. About 14.3 grams, absolutely phenomenal : r/rosin) – that’s the kind of result you can expect when dialing in this cultivar for production.
